1.The black market will move on......Plus there will be people who will still deal ganja as there will be plenty under 18 year olds who will require it.
Do people deal alcohol to minors? No.
Does the black market ever stop moving? No.
Why do either of the points you made compramise the points they were attempted responses to?
2.The gateway drug effect will pretty much stay the same as the kids who for some reason felt the need to smoke ganja will just find some drug to substitue it which will probably cause more harm.
The gateway drug effect does not come from a desire to become more intoxicated, it comes from peer pressure and the exposure to an illegal drug culture.
Take away the illegal drug culture support and the gateway drug goes away as well.
3.It would be extremly hard to prove that parents were supplying their kids. And I dont know about in america but in the UK kids can drink at home so it might be the same for ganja.
If it would be so hard to prove this sort of situation then why have I personally seen people get in trouble for this on both the local and national levels?
4.The money they would rais could be used to help people quit.
How can you raise the money if people like you are trying to make sure it is always illegal?
5.I doubt it would decrease much if at all noticeable.
You just don't know what you are talking about then.
There is a size-able population of inmates who were sentenced to prison time for trafficing, possessing, and using Marijuana.
Plus, even if the population was low, saving one decent person who happens to smoke pot from the horrors of prison is worth it.
6.Doubt it would decrease but instead increase.
I bet you doubt a lot of things, does that mean you are correct? No.
If marijuana was legal, then every marijuana "offender" would not be commiting a crime, hence, the non-violent crime levels would have to go down (with regard to marijuana).
Spikes in other non-violent crimes are not the issue at hand.
7.If your silly enough to do it even though you know its bad for you....then its natural selection.Its banned for a reason.
Natural selection?
Then why do you oppose the free use of this drug?
Are you worried about people you love and care for naturally selecting themselves out of existance?
And on top of all this, I still have not seen you give a reason for why marijuana is banned other than because it is illegal.
